'particle' not declared in this scope

[Tino52]

Hi I don’t understand what wrong in my code:

This is the partial code
…
float PressV;
…
void setup()
{
Serial.begin(9600);
Time.zone(+1);
Particle.variable(“PressV”,PressV);
}
and this is the error message
stazmeteovisala.cpp: In function ‘void setup()’:
stazmeteovisala.cpp:42:1: error: ‘Particle’ was not declared in this scope

Thanks Valentino

Could you share the link of your project from the Web IDE? That way we can have a look at the exact project without having to make guesses.

When trying to edit the title of you post, Discourse told me I couldn't because there was already a topic with the exact error description as yours. Had you tried looking for that already?

'Particle' was not declared in this scope

I am using the Web IDE to compile two previously working Particle Core applications and I get the “‘Particle’ was not declared in this scope” error with the line number pointing at a “Particle.publish” function. This is unchanged and previously worked. Reverting back to “Spark.publish” removes the errors, has something changed in the Web IDE or the firmware compiler?
